Dead Whirlpool dishwasher

[NVRGVUP!]

I am new here. Ok I am mechanical but not Electric or circuit savy. I can trace a circuit and wire stuff but That Green Board with little things all over it is an EVIL Nemesis.  

Prob item , Whirlpool Dishwasher. Model # WDT780SAEM2.  

Issue:  User interface panel. No lights.  Filled with water. came back the next morning. Nothing . no lights. I have voltage detector that is blinking and chirping while I pass it along all the wiring. I bailed the sump out and washed the filters. I tried the turn off power and let sit. ½ our, 1 hour, 24 hours,   etc.  I looked underneath and no leaks.  I have a very good supply parts house here in town. he gave me some tips but can't help to much. 

This was purchased from Home Depot if that is a help.  I can't start switching out parts and narrow it down. I am leaning to the user button console. that would be my limit.

I owned an Asco European  basic model that I piked up cheap 15 years ago. It lasted 12 years. The sales rep seemed shocked as they were not known for their longevity. 

the interface / user buttons console is 87 plus tax. the whole computer is 200.  WE just bought this in 2016.  I live 40 mile from Greenville ohio. THE MUTHERSHIP! That is where this puppy was born. I have known folks who work there. Darke County Ohio. Home of Annie Oakley and the largest county fair in the country. Why are they doing this? LOL.
